Seoulfull reports that Ms Chung had made a phone call at 2:30 p.m. that day, stating that she couldn't handle the pressure of contract and work problems and that she wanted to die.
For the person thinking about suicide, that kind of call is a cry for help. It's often a desperate, feet-on-the-ledge cry for help that should not be ignored. (And in case you're wondering, yes, I have been in that call-receiving position. I was a teenager at the time and didn't fully understand what was happening, although in the end tragedy was averted.)
Sadly, though, even if someone takes that call and tries to help their suicidal friend or loved one, too few people know of what resources are available to them in South Korea, and that perceived humiliation associated with mental health services prevents people from going even if they do know how to get it. As I've said, the Korean media needs to do something — right away — to end that impression.
